Professor Miller spent his career at Cornell University, where he was emeritus. His writings ranged widely over philosophy of science, ethics, metaethics, political philosophy and Marx. He wrote some brilliantly synoptic books on all these topics, including Analyzing Marx (which is, oddly, omitted from this obituary). Comments are open for remembrances from those who knew Professor Miller, or for those who wish to comment on the significance of his work.
(Thanks to Phil Gasper for the pointer.)
